MARKER.

Application filed September 25, 1923. Serial No. 664,671.

This invention relates to markers such as are used for marking lines on athletic fields, tennis courts, and for marking safety and traHic zones on streets and highways, lo cations and aisles on factory and garage floors, etc.

This invention has for its salient object to quickly and effectively mar-k well-defined lines on the desired surface.

Another object of the invention is to spread the paint or other marking material uniformly on the surface to be marked and to accomplish this result effectively where the surface is even and level or rough and uneven.

Another objectof the invention is to pro vide means in connection with a marking de vice of the character described for transporting a supply of marking material for manipulating the marker and for storing the marker when not. in use.

F urther objects of the invention will appear from the following specification taken in connection with the drawings, which form a part of this application, and in which Fig. 1 is an elevational view partly broken away and partly in section showing a marker constructed in accordance with the invention and mounted upon or suspended from a wheeled truck.

Fig. 2 is a top plan view of the construction shown in Fig. 1.

Fig. 3 is a rear elevation-0f the construction shown in Fig. 1.

Fi 1 is a sectional elevation. taken substantially on line H of Fig.1.

Fig. 5 is a side elevational view'partly in section showing the means for supporting the marking device on the framework carried by the truck.

Fig. 6 is a detail elevational view partly in section and on an enlarged scale showing the 0 erative parts of the marking device in raise position. b Fig. 7 is a top plan view of the construction shown in Fig. 6. Y

Fig. 8 is a rear view which shows the parts in the position taken when the device is not in operation.

in the positions when the device isoperating on an uneven or rough surface.

Fig. 10 1s a-view similar to Fig. 6 but showing the parts in their operating position- Fig. 9 is a similar view showing the parts i The invention briefly described consists of a marking device comprising side plates, a plurality of fingers arranged side by side and loosely pivoted on a rod extending betweensaid side plates and a plurality of disks or washers loosely mounted on another rod also mounted between said side plates. The washers or disks cooperate with the fin gers and means such as a cam is provided for engaging and lifting the fingers and at the same time lifting the washers. This action illustrated in Figs. 6 and 8 elevates the fingers out of contactwith the round and also stops the flow of the marking fluid. As shown in Fig. 9, the fingers by reason of their being loosely pivoted are adapted to follow depressions in and elevations on the surface on which the markeris beingused. The marking device may also havepivoted between the side plates, runners adapted to follow the surface in a manner similar to the fingers.

The marking device just described may be suspended from any suitable vehicle or truck or may be propelled in an desired manner. In the particular embo iment of the invention shown, this marker is suspended below a truck having a supply receptaclefor the marking fluid and a tank adapted to receive the marking device when the device is not in use. This tank preferably has kerosene or someother suitable liquid therein beneath which the device can be submerged to prevent rusting and to remove the paint or marking fluid thereby preventing the device from becoming gummed and inoperable. Further details of the invention will appear from the following description.

The marking device will first be described and attention is particularly directed to Figs. 6 to 10 inclusive. This device comprises a pair of side plates. 10 and 11 rigidly connected by cross rods 12. In addition to the cross rods 12, a cross rod 13 is secured between the plates 10 and 11 and has pivoted thereon at its ends adjacent the inner surfaces of the plates 10 and 11, drop plates or runners 1 1, the adjacent sides of which contact with one another. These runners are loosely pivoted on the rod 13 and are adapted to follow the surface on which the device is being used.

A spindle or axle 16 is also secured to the plates 10 and 11 and extends through slots 17 formed in the plates orrunners 14. A
